1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Phospholipase A (PLA) activity, as measured by the accumulation of (14)C-lysophosphatidylcholine in leaves of tomato plants, increased rapidly and systemically in response to wounding. The increase in PLA activity in the systemic unwounded leaves was biphasic in wild-type tomato plants, peaking at 15 min and again at 60 min, but the second peak of activity was absent in transgenic prosystemin antisense plants. Supplying young excised tomato plants with the polypeptide hormone systemin also caused (14)C-lysophosphatidylcholine to increase to levels similar to those induced by wounding, but the increase in activity persisted for >2 hr. Antagonists of systemin blocked both the release of (14)C-lysophosphatidylcholine and the accumulation of defense proteins in response to systemin. (14)C-lysophosphatidylcholine levels did not increase in response to jasmonic acid. Chemical acylation of the lysophosphatidylcholine produced by wounding, systemin, and oligosaccharide elicitors followed by enzymatic hydrolysis with lipases of known specificities demostrated that the lysophosphatidylcholine is generated by a PLA with specificity for the sn-2 position.
